Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
Checking and replacing tires
Tread wear indicator
CHECKING YOUR TIRES
Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built- in tread
wear indicators to help you know when the
tires need replacement. When the tread
depth wears to 1.6 mm (0.06 in.) or less,
the indicators will appear. If you can see
the indicators in two or more adjacent
grooves, the tire should be replaced. The
lower the tread, the higher the risk of skid-
ding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).
Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a techni-
cian and have the tire repaired or re-
placed.
Even if the damage does not appear serious,
a qualified technician should examine the
damage. Objects which have penetrated the
tire may have caused internal damage.
Any tires which are over six years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they have
never or seldom been used.
This also applies to the spare tire and tires
stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as original-
ly installed and with the same or great-
er load capacity.
Using any other size or type of tire may seri-
ously affect handling, ride, speedometer/
odometer calibration, ground clearance, and
clearance between the body and tires or
snow chains.
